Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Mannequin Syndrome is launching in Early Access to deliver a strong, atmospheric horror experience from the very beginning—while working closely with the community to shape the future of the game. The goal is to gather valuable feedback on gameplay mechanics, mannequin behavior, level design, and co-op balancing. Early Access allows us to refine core systems, expand the world with new maps, and introduce additional mannequin types and rituals based on player input. Your support will help guide development as we evolve the game into a deeper, more terrifying experience”

Approximately how long will this game be in Early Access?

“We expect Mannequin Syndrome to remain in Early Access for approximately 12 to 18 months. However, this estimate may adjust depending on community feedback, development progress, and the complexity of planned content additions.

Our objective is to polish the core gameplay, introduce new maps, expand mannequin types and AI behavior, and enhance the overall horror experience until the game reaches a complete and satisfying state for players.”

How is the full version planned to differ from the Early Access version?

“We plan to expand Mannequin Syndrome beyond its Early Access version by introducing additional levels, mannequin types, and more complex ritual mechanics. Each new map will bring unique visual themes, AI behaviors, and investigative challenges that deepen the horror and replayability.

During Early Access, our focus will be on polishing core gameplay, balancing mannequin AI, and refining existing systems through community feedback. The full version is intended to include more maps, survivors with small storylines, enhanced environmental interactions, and new ritual variations—shaped by what players find most compelling.

Please note that the final content and feature set may evolve based on testing and community involvement throughout development.”

What is the current state of the Early Access version?

“The Early Access version of Mannequin Syndrome includes two fully playable investigation zones, featuring distinct atmospheric designs and unique mannequin types. Both the Classic and Broken Mannequin variants are implemented, each with their own AI behavior and haunting mechanics.

Core systems such as multiplayer co-op (1–4 players), flashlight handling, task-based progression, ritual mechanics, and the player death/spectator flow are already functional. Environmental puzzles and safe zone logic are also in place to enhance immersion and tension.

This version reflects the foundation of the game's horror investigation loop. Future updates will bring bug fixes, visual improvements, new maps, more mannequins, expanded lore, and additional game mechanics based on player feedback.”

Will the game be priced differently during and after Early Access?

“We plan to offer Mannequin Syndrome at a lower price during Early Access to reflect the ongoing development and to reward early supporters. As more maps, mannequin types, and features are added over time, the price may increase when the game leaves Early Access.

Any changes in pricing will be announced in advance to ensure transparency and give players a fair opportunity to join before full release.”

How are you planning on involving the Community in your development process?

“We plan to involve the community primarily through our official Discord server, where players can share feedback, report bugs, and suggest improvements directly with the developers.
We'll also be inviting members to participate as beta testers, allowing them early access to upcoming content and features before public updates are released. This collaborative approach ensures we can shape Mannequin Syndrome based on community insight while delivering the best possible experience”

About This Game

Mannequin Syndrome is a first-person co-op survival horror game for 1–4 players.

You are sent into the Syntrax Facility, where something has already gone terribly wrong. The building is still running, but not the way it should. Some systems remain active. Some areas still function. And throughout the facility, mannequins stand motionless like empty shells.

Most of them are inactive.

One of them is not.

The active mannequin does not always stay the same. At any moment, the one hunting you can become still, while another somewhere else becomes active instead. That means every mannequin in the facility can become the threat.

Your objective is simple on paper: enter the facility, restore critical systems, complete the required objectives, reach the shutdown sequence, and escape.

Surviving long enough to do that is the real problem.

The deeper you go, the worse the situation becomes. Every completed objective moves you closer to escape, but it also makes the threat more dangerous. What begins as something slow and unsettling becomes faster, more aggressive, and far less predictable.

The challenge is not only staying alive, but continuing to progress. Exploration, objectives, and coordination all become harder as the threat escalates. To survive, you will need to restore access, open new paths, interact with terminals, solve puzzles, and keep moving forward under pressure.

The mannequins are not there just for atmosphere. They are the main threat. As the round progresses, they become more relentless, more dangerous, and harder to read. And once the endgame begins, the facility stops feeling like a place you are exploring.

It starts feeling like something you need to escape before it fully turns against you.
